(hypothetical) 1500hp M10 build

[Hova]

I've had some drinks, and got lost on the interwebz. I know all of you know of the famous BMW motors of the turbo F1 days, but realistically what would it take to build an M10 to lets say 800hp, or even 1000hp? Judging by the photos and videos I've seen, it looks like a stock M10 block and crank. Obvious the pistons and rods are one off pieces. The head looks like an S14 head, but it's split covers like the M10, so perhaps something else? Has anyone gotten close to those those power levels with an M10?

Just going through my head here:
Take an M10, sleeve it down to 1.5l
Forged rods
custom pistons, possibly CR or 8:1 or 8.5:1
16v head (S14 head bolts on, but oil return needs to be modified I believe)
External oil pump
Huge ass cams.
Big turbo
Wastegate welded shut.

800hp.

Edit: Looks like the head is not from an S14, but a special head BMW made for their F2 team:

So it's possible to get a hold of one (maybe).


Lay it on me thick gents.

After having looked at the m10 block versus a m52 block it’s considerably less robust.

Having made 800hp and 1000hp on a m52 I cannot imagine doing it on a m10 Without serious work.

The answer to how the 1500 hp qualifying engines were possible lies in the bore and stroke that was used, the cylinder head flow, and the resulting rpm range. Running toluene as a fuel helps too.

But in any case technology has marched on since the late 80’s and if you want to build a 800 or 1000 hp s14 or even m10 headed motor, you can certainly do so, and would not even need to be that wild of a build.

Having a new engine for every session helps too.

the head on the f1 car is different than the s14. I believe it was the m12.

The most important thing never stated is:

- a team of 50+ engineers constantly reading data from many sensors and custom tuning every last issue out of the engine to have it just inside the hairy edge of being an external combustion engine.
-1000 hrs of engine dyno time

Parts:
-Dual stage injectors
-ITBs (which are so hard to tune with a turbo too)

Weren't they running 80+ psi to get to that 1400hp? A 1400hp 4cyl doesn't just come from a simple bullet-ed list of parts. It takes man and brain power...the likes of which we don't possess individually. 1K hp is a feat itself, then you still have 400hp to find. Insane.

Probably the best stash of info on it

I mean honestly...shouldn't a sleeved 3.2 S52 make a shit ton of power? I'm sure it would not be to far fetched to have it machined. I bet 1500hp is capable with honestly not TOO much money. I'm thinking 1200whp? Past that, you can only do so much with xx. Bore and xx stroke hence v8s making upwards of 2500hp currently. I mean lets be realistic, we are all here because Inline 6 power... not JUST power the super special awesome power. If we wanted lame power we'd do it.
